Warning: SPOILERS for chapter #80 of BorutoBoruto's huge twist that completely changed the series with an in-story retcon will be permanent, according to the series' biggest villain. After Kawaki used Eida's power of Omnipotence to change reality and make everyone believe that he is the Hokage's son, and Boruto is the outsider who betrayed Konoha, fans are expecting that the hero will be able to fix everything in the future, but according to Momoshiki Otsutsuki this will never be possible.
